Ok, I've applied that on the next/late branch for arm-soc now, and one patch
on top that removes the NR_IRQS definition from mach/irqs.h

This is in another subsystem, so I'm not applying this to arm-soc, but
the warning should be gone with my one-line change to remove NR_IRQS
anyway.
Linus, if you want to put it in the gpio tree for v4.7, feel free to
add my Acked-by: Arnd Bergmann <a...@arndb.de>, otherwise I guess it's
enough to have this in v4.8.
